How are map frames related to the layout?
Maps on a layout exist within map frames, which are containers for maps. A map frame can point to any map or scene in your project. The map frame and the map view are independent, so zooming or panning in the map frame does not affect any open map views. Map frame constraints allow you to set limits on the map extent.
